    dribbling. Dribbling is all based on conservation of energy and the two different types of collisions, elastic and inelastic. The more air pressure a basketball has inside it, the less its surface will bend or deform during a bounce, and the more its original energy will be stored in the compressed air inside (Bill Willis, 2001). The reason for this is that the air inside of the ball can return the energy of the ball better than that of the material of the ball, which is usually leather. This is the

    The goal of electric vehicles is to reduce air emissions associated with typical internal combustion vehicles (ICVs), thereby decreasing the emission of environmentally damaging products such as carbon dioxide and nitrogen oxides. Since electric vehicles run on electricity generated from batteries and do not emit air pollutants, these vehicles are termed zero emission vehicles (ZEV). CARB mandated that ZEVs be 2% of the total automotive sales by 1998 and 10% by 2003. The push for ZEVs raises serious
